Underwater anti-dispersion repairing material for hydraulic structure and preparation method thereof
The invention discloses an underwater anti-dispersion repair material for a hydraulic structure and a preparation method of the underwater anti-dispersion repair material. The repair material is prepared from the following raw materials in parts by weight: 30-40 parts of cement, 10-15 parts of fly ash, 5-10 parts of micro-silica fume, 15-25 parts of magnesium oxide, 4-7 parts of ammonium dihydrogen phosphate, 0.5-1.5 parts of an anti-dispersion agent, 0.5-1 part of fiber, 0.1-0.5 part of a water reducing agent, 1-2 parts of a retarder and 10-15 parts of water. The underwater anti-dispersion repair material for the hydraulic structure has the characteristics of short setting time, high early strength, good anti-dispersion property, good adhesion between new and old interfaces, good construction performance and the like.
本发明公开一种水工建筑物水下抗分散修补材料及其制备方法，该修补材料由以下重量份的原料组成：30~40份水泥、10~15份粉煤灰、5~10份微硅灰、15~25份氧化镁、4~7份磷酸二氢铵、0.5~1.5份抗分散剂、0.5~1份纤维、0.1~0.5份减水剂、1~2份缓凝剂、10~15份水。本发明的水工建筑物水下抗分散修补材料具有凝结时间较短、早期强度高、抗分散性好、新旧界面粘结力良好、施工性能良等特点。
